Retrieves an object indicating whether the specified Microsoft?DirectAnimation?behavior is running.
Syntax
HTML N/A Scripting [ oOn = ] object.onOffBehavior
Possible Values
oOn DirectAnimation Boolean (DABoolean) object that specifies one of the following values.
true Behavior is running. false Behavior is not running. The property is read-only. The property has no default value.
Remarks
This property is deprecated.
This property allows you to incorporate multimedia elements, such as 2-D and 3-D animated images and sounds, into an HTML page using the anim:DA element. The object this property is applied to must be an HTML object with a valid HTML+TIME (Timed Interactive Multimedia Extensions) timeline. Use this property with HTML+TIME timelines to control DirectAnimation content. This property is not part of the HTML+TIME specification.
Note To ensure that pages using this property display properly in Microsoft Internet Explorer, complete the following steps.
- Use #time instead of #default#time for the behavior declaration.
- Include the time object in your page. The class identifier used to specify this object is 476C391C-3E0D-11D2-B948-00C04FA32195.
These actions are necessary only for pages that use HTML+TIME timelines to control DirectAnimation content.
Example
This example attaches a timeline specified with HTML+TIME to an image animated with DirectAnimation. The onOffBehavior property is used to display one image while the animation is running, and to display a different image while the animation is stopped.
<HTML> <HEAD> <TITLE>progressBehavior</TITLE> <XML:NAMESPACE PREFIX="anim"/> <STYLE> .time { behavior: url(#time); } anim\:DA { behavior: url(#default#anim); } </STYLE> <OBJECT ID="time" CLASSID="CLSID:476C391C-3E0D-11D2-B948-00C04FA32195"> </OBJECT> </HEAD> <BODY> <P>An image of the sun is displayed before the DirectAnimation behavior starts. Five seconds later, a new image replaces the image of the sun. The new image fades out during five seconds of animation, and the original image of the sun reappears.</P> <SPAN ID="spanImg" CLASS="time" t:TIMEACTION="visibility" t:BEGIN="5" t:DUR="5"> </SPAN> <DIV ALIGN="center"> <anim:DA ID="da1" STYLE="width:504; height:126; z-index: -1;" /> </DIV> <BR> <BUTTON onclick="spanImg.beginElement();">Restart</BUTTON> <SCRIPT LANGUAGE="JScript"> <!-- // Assign a variable to the DA statics library m = da1.statics; // Create the DAImages img1 = m.ImportImage("../../common/solarsys.gif"); img2 = m.ImportImage("../../common/sun.gif"); // Display image 1 while the behavior is running, and // image 2 while it is stopped. img3 = m.Cond(spanImg.onOffBehavior, img1, img2) // Animate the opacity of the image from 100% to 0%, based on the // progress of the time behavior. Use (1 - progress) to get the // proper opacity. img4 = img3.OpacityAnim(m.Sub(m.DANumber(1),spanImg.progressBehavior)); // Set the image of the DA Object to be the final image behavior da1.image = img4; //--> </SCRIPT> </BODY> </HTML>This feature requires Microsoft?Internet Explorer 5 or later.
